Application filed July 7, 1908.

vfIe it known that I, BERNHARD MONTGOM- nRir'BnsKow, a citizen of the United States residing at New York, N. Y., have invented certain new and useful Improvements yin i Motor-Trucks, of which the following is a specification.

My invention relates to improvements in`- motor vehicles, and is more particularly designed for use in vconnection with heavy trucksand drays, where great tractive eiect is '1`1ecessary`,v

In connection with vehicles of this character, it is extremely desirable when traveling with heavy loads to provide some means,

J .whereby the dead load of storage batteries,

motors and accessories, is supported free from the body proper. of said truck; but it is also necessary that a certain amount of ythe live load can if necessary be placed over tliedriving wheels so as to give'an increased f adhesion between said wheels and the grc'uind.A

One object with my invention 1s to pro! vide an independent tractor in elastic cony .nection with'the body of the truck.

j Another object is to enable the driver of the truck to increase the load over the driving wheels to such an extent as he considers necessary so as to prevent slipping in going uphill and "to reduce the weight over the. saine wheels when speeding on llevel road.

Another object is to provide a construction, whereby the bodies of the present :horse :driven trucks and drays may be utilized iffso desired..

- Myfpresent'invention is designed to secure .these objectsand to this end it includes the `novel features of construction hereinafter vc lescribed l'and particularly pointed 'out in fthe appended claims.

Y A vmotor truck constructed in accordance inventionisillustrated in the accompanying drawings, in which:-

are details 'of the-traction varying device. Fig. 7 is a side elevation of a dray with both front and rear steering wheels and with the tractor placed between them.

Referring by reference characters to the drawings, the numeral 1 designates the body, and 2 and 2a the front and rear axles respectively, to the ends of either or of both v"of which, the steering wheels (3) are connected by the usual knuckles operated in the mannerwel'l understood by those skilled in.

tions of the guides are located the upper springs 9 and 10 atthe front and rear respectively, while between the brackets'and the lower ends Aof the guides are similar springs 11 and 12. By this arrangement an elastic connection is secured between the front and rear ends of the fraine of the tractor and the body of the vehicle. storage battery or the gasolene motor and accessories are carried at one end of the ytractor frame and preferably upon independent frames, supported from the frame of the tractor, and each tractor `.traine is supplied with its own driving wheel'or wheels. In carrying out this arrangement, I provide two tractors with frames designated as 8a, 8b, respectively, and sub-frames` 11a and 11", for storage batteries or gasolene motors and accessories upon the `front portions of the frames 8a, and 8b, respectively. 'For electrically driven trucks I would locate the motors 12a and 12b, at the rear of the tractor. I .Y

From pinions 13 on said motors or from the pinions 13a, and 13", onthe gear cases 141%, and 14", extend chains 15a, and 15b, to the sprockets 16a, and 1Gb, on the driving wheels, which may be common traction en- Lgine wheels or chain wheels or Wheels of any other suitable construction.

"I prefer to provide two driving wheels,

The amount of the vertical motion ofthe platforms is controlled by spiral cams (28) in connection with gear wheels (29) and screws (30), which screws are driven by sprockets 31 and 32 and chain (33). The screws and gear-wheels on the opposite side of the tractor or tractors are all operated' simultaneously `by turning the hand wheel 34'at the side of the driver. IThe connection'l between this .wheel and the screw shaft may be by. shaft and 'bevel gear drive or by chain yby turning the hand wheel in one;v direction,

the upper springs 9 and 10 are compressed,

reducing 'the strain on the kspriifig's on the front and rear steering-wheels to a certaln susl extent and throwing an additional load on the; driiving wheels ofthe respective trac.- tors. Should the upper and lowerarms of. the springs (9) be brought into contact with each other, the entire load wouldbe practi.

callyv carried on the tractors andi therna'xi-l vmum adhesion reached. f
